EVLSTNRG011-150 12 V 150 W power supply based on STNRG011 digital combo and SRK2001 adaptive synchronous rectifier controller Data brief Description The EVLSTNRG011-150 is a 12 V, 150 W power supply demonstration board for 90 V ac to 264 V ac mains, which is representative of an AC/DC converter for an all in one (AIO) computer or a general purpose high power adapter. The design is based on the STNRG011 IC, a digital combo that controls a two-stage AC/DC SMPL. The front-end is a transition mode PFC pre-regulator and the second stage is an LLC HB resonant converter. The SRK2001 implements the synchronous rectification in order to obtain Features higher efficiency. Digital controller: STNRG011 No auxiliary supply is needed due to the very low TM PFC with resonant HB-LLC converter consumption at no load. Input voltage range: 90 264 V ac A full set of auxiliary functions and protection is 12 V 5% CV output regulation also provided, this allows reduction of the overall BOM while maintaining a rugged design. Full-load power: 150 W continuous operation The performances of the EVLSTNRG011-150 can Peak power loading: 200 W meet the requirements of major standards Full-load and average efficiency: greater than ENERGY STAR for computers ver. 6.1, EuP Lot 90% at 115/230 V ac 6 Tier 2, European CoC ver. 5 Tier-2, in terms of Peak efficiency: greater than 93% efficiency, no-load input power and power factor and feature harmonics content well below the No-load mains consumption: less than 75 mW limits of European Standard EN61000-3-2 Class- Hold-up time: greater than 10 ms D and Japanese standard JEITA-MITI Class-D Full set of programmable parameters regulations. High flexibility thanks to the configurable NVM Black box functionality with the installed EEPROM February 2018 DocID031500 Rev 1 1/6 For further information contact your local STMicroelectronics sales office. www.st.co.
